Legacy systems are computer components that are still in use despite the fact that they are running on old technology, including old school hardware features. They are still used because they form a large, rather bulky yet very important part of the organization in terms of the work they get done, and also their complexity. Furthermore the costs an organization would incur should they attempt to switch to a newer system are exorbitant enough to be discouraging. Therefore replacing a legacy system can turn out to be costly both monetarily and also productively. With that in mind, organizations not willing to lose these old generation systems choose to try and bring them into the future with the help of current technology – especially with regards to the hardware aspect. If there were a way to emulate the legacy system while using current technology, it would make the process of legacy integration easier. Also, if it were possible to use technology that can allow legacy systems to interact with modern hardware components, then legacy integration would be made practically effortless for the experienced software technician. However, in spite of how these methods of legacy integration sound simple and inviting, there are several obstacles that typically present themselves. For starters, considering that the creators and designers of the legacy system may not be there anymore to assist with the system, it may be difficult to fully understand the system. Furthermore, after years of maintenance, upgrading and several changes, the system will not be as it was originally designed, and the documentation if any may not be complete, or may even be...

WebLogic Server performance and memory issues are not uncommon from time to time. This is quite natural for many applications, especially when in the growth period of the application or during processes that involve adding new features and functionality or new users to the system. In some cases, developers who write code are not necessarily able to predict how applications handle the load or will be used. The net effect of this can be a performance problem, with some of the commonly seen problems being application crashes resulting in out of memory errors and slow response times. The good news is that there are technical reasons why systems function in the manner they do, and that these performance problems can be solved. The main challenge when trying to fix WebLogic Server performance and memory issues is getting processes in place one at a time to handle the problem until the system becomes more stable. The next step involves you changing your process so as toincorporate best practices in your development life cycle, which may help you avoid similar problems in the future. Technical commitment to the project is required when trying to identify and solve the issues at hand. Solving your WebLogic Server performance and memory issues requires you to begin your efforts with the fundamentals. It is generally recommended that you think about creating small independent work groups to kick start WebLogic Server performance and memory use improvements in the following areas: Java: This is the foundation of the WebLogic server application. The best place to get information on a poorly performing application is from that application itself....
